Low energy alpha-nucleus optical potentials are an important ingredient of reaction cross sec- tion calculations relevant in various processes of heavy element nucleosynthesis, such as the astrophysical γ-process. The optical potential can be studied directly by high precision alpha elastic scattering experiments. In the Institute for Nuclear Research (Atomki) a systematic study of the optical potential has been carried in the last 15 years. One of the last studied isotope was the64Zn, where complete angular distributions were measured at two energies close above the Coulomb barrier. Through the example of this study, the experimental techniques needed for a precise alpha elastic scattering measurement will be presented.
This research was realized in the frames of T ´AMOP 4.2.4. A/2-11-1-2012-0001 “National Excellence Program Elaborating and operating an inland student and researcher personal support system” The project was subsi- dized by the European Union and co-financed by the European Social Fund.
